Hi.
While playing games my Xperia Play produces lots of heat. The back of the phone, and the gamepad feels really warm.
I checked the temperature with Battery Monitor Widget and when I don't use the phone it stays around 25-30 degrees Celsius, but when I play games (even 2D ones) it goes up to 38-40.
Is this a normal thing or there's something wrong with my battery ?

I can confirm this happens. Basically it is using more charge, therefore as a side effect of that it produces more heat from the chemical reaction. Same thing when you have it charging.
It isn't horrible, but try not to let it get too hot as it may shorten the lifespan of the battery.
So this is true for all xperia plays that after some time of gaming the phone will be really warm ?
The phone will get warmer, of course... but 40 degrees is not excessively hot. It feels warm in your hand, but it's not dangerous. A dangerous temperature would be close to 50.
The highest temperature that I had was 44 degrees after a long Nova 2 session.
I am a bit worried by the fact that while browsing the net through wifi the battery heats up to 38 degrees, but it's okay as long as it's less than 50 :> ?
Thanks for the help.
I'd say if it goes above 46 or 47 you just switch it off for a while. Not only because you don't want to overheat it, but because running the phone on higher temperatures reduces battery life (higher temperature means higher resistance to conductivity for metals).
Thanks for the into that it's perfectly normal for the phone to feel warm.
Have you ever reached 50(or that 46,47) degrees on Xperia Play or any other phone ? What app made your battery that hot ?

My former phone, the Galaxy S had HUGE issues with temperature while using 3G. Every time I toggled it on, the phone became awfully hot and the battery drain skyrocketed. I got it on 53 degrees once, since it was in my pocket. I was a bit scared, but the phone resisted it. Still, it wasn't pleasant.
The advantage of the Xperia Play being bulky and plasticky is that it's hard to bring it to extreme temperatures. If it's hard to make it hot, it has a positive impact on battery life as well.

Yea, this happens to me all the time. When using anything that drains my battery it heats it up as well.
All batteries release heat as current passes through them. When the phone is idle, the heat released is low enough your hand doesn't feel it. As the current increases while gaming, so does the heat.
It's nothing to worry about. The batteries are designed to handle heat without being damaged.
Especially since android devices are becoming more popular in places like india, where there's a lot of ambient heat.

I am using G2 F320L. It is very good set. but i have problem that its battery temperature rises up to 45 degree Celsius (centigrade)!
When temp rises, it can observed physically (handset feels hot on palm).
Please tell what is upper safe limit for battery temperature?

Probably that's a reasonable limit - from own experience I have to tell you that if the phone stays hot for a long time you may damage the screen (yellow spots), so try to keep it cool somehow if you are doing CPU heavy things - for example, when flashing it, I keep it on a pack of cheese from my fridge. It works though :silly:
Back on the HTC one x the battery to be classed as over heating with 48c.
So anything under 50 is OK, though I wouldn't want to sit up st that limit for long periods of time.
I've never seen the battery get about 45, and considering I've seen my CPU get up to 92C (at which it turns off the phone) I say its a safe temp.
Just to clarify my phone didn't do that on its own the default is to throttle and keep the CPU below 75. I turned that off and sat my phone on a fan to see what I could push kitkat too in antutu.

Thanks!
Thanks for useful info!
Now i concluded from above comments that temp under 50 centigrade is ok but not for longer time!
Seems the Nexus 6p has a cold bug. First phone i seen this in.
So i been doing some overclocking and bench marking on a few devices. The Nexus 6p has shown some strange behavior. When i had the phone chilled and ran some benchmarks the battery would drop drastically. Restart and all that did nothing. The batt. stayed at 39% for about 2 hours with some heavy use. Charged it back up no issues. Did it again and it did the same thing. Took my turbo 2 to an even lower temp and that was fine it did not have this.
Something you have to worry about? Nope not unless you are out in Alaska or taking a trip to the artic circle. However if you do this could cause you some issues.
Tested on a stock room and kernel. As well as a purenexus and elemental x combo. Same outcome.
Again not really an issue. And the Nexus camera visor and display survived the -40c freeze and back to room temp test. Attached is a pic of the massive drop
Not sure why the Droid Turbo didn't demonstrate this same behavior, but extreme cold temperatures definitely have an impact on lithium ion batteries. Perhaps the material of the Droid Turbo insulates the battery a bit better than the aluminum on the 6P?(pure speculation there - science geeks, feel free to rip that one apart)
I've experienced the same thing with my DSLR (Nikon D80) when shooting in the cold.

Yeah the turbo 2 was even exposed to cooler temps longer. And its not that the capacity was lost. After the bench it would stay at that + for a few hours before it started going back down. So when i started at about 74% after it still had 74% less just android was saying that it was lower. I still managed to get a full charge out of it. Not an issues just a omg my batt is almost dead. Fallowed by omg my battery has been at this % for a few hours.
-40°C isn't really common weather and is definitely out of normal range of temperatures. I live in a area where it gets cold (-30°C) during wintertime, I don't really use phone in a such coldness (my fingers would freeze pretty fast anyway.)
I once answered phone in -25°C (current phone at the moment was Sony Ericsson W910i) I talked for 15 minutes and my battery went from 100% to 21% and shut down moment after the call ended.
Don't all batteries exhibit fluctuations in total output in extreme situations high or low? I use an iphone in a work truck that is left outside in 20f to 30f temps and that thing is crazy swinging from 100% charged when I leave it in truck to dead in one night in cold temps.

My nexus 6P sorta died on me today, it was stored in my GF's bag, we were outside, 0F, for like an hour. When I go to take my phone, won't turn on, tried plugging it in, nothing.. could the cold weather (not so cold) have killed my nexus 6P ? Anyone has had this problem ?
I live in northern Finland and I have experienced this kind of behavior with my 6P lately. The battery dies suddenly under -10 C degrees if I keep it in my pants pocket. This is daily problem so have to wear my phone in wool mitten and then pocket it.
I think this started right after 7.1 update. My phone is 12 months old so it might be the battery losing its best edge or simply software feature/bug.
The battery model uses inputs from current flowing in/out in the battery, outter voltage and battery temperature sensors and calculates Open Circuit Voltage leading to the estimated State Of Charge (by use of a 3 degrees polynom)
As any resistor, the internal battery resistance will vary depending on temperature. So will the OCV calculation.
All these parameters are linked non linearly and the models are done within temperature ranges (different coefficients for say different temperatures). If temperature exceeds thresholds ( /sys/class/power_supply/bms shows a nominal range of [10 degC, 45 degC] ), the SoC will not be computed.
If temperature exceeds thresholds or SoC varies too widely, the battery current will be downlimited, meaning it won't charge as expected or could shutdown for safety reasons.
If battery temperature goes under 5 degC, the SoC is considered invalid.
As such when starting again the device within this range the SoC will be calculated again correctly and the device will stay on.
There are also high/low safety thresholds which will instantaneously shut off the device (I think they are stored in the Qualcomm IC so I can't see these values).
So while the battery can probably work fine under 5 degres C, the SoC won't be calculated properly. You can also get some feedback from the known battery health in /sys/class/power_supply/battery/health (Good, Dead, Warm, Cool, Cold, Overheat, ...)
I've gathered this information from the Qualcomm IC driver source
Sound like a Overclocking CPU with Liquid nitrogen haha.
This just happened to me today. I was out skiing and temps were -10 f. Phone shut off in less than an hour after starting from 100%. Went back inside, warmed up the phone and the battery was stuck at 39%. I moved my phone to an interior pocket closer to my body and didn't have a problem for the rest of the day.
As a avid skier, I can say I've always had extreme cold weather issues with phones, but the Nexus 6p is definitely the most severe.
FYI I'm on 7.1.1
This happened to my Nexus 6 today. I was in the garage (non heated) working on my car and had my phone sitting on a box next to me. It was about 30°F and I grabbed my phone to send a picture of something to my friend. As soon as I launched the camera it shut down. It booted instantly after pressing the power button, but after being on for about 15 seconds the battery percentage displayed in the status bar suddenly went from 51% to 0% and it shut down again. After bringing it inside to warm up my battery was back to 50%.
I've also taken my phone snowboarding in much colder temperatures and never had this issue. Even while using it on the chair lift where it's directly exposed to the cold and wind it's never shut down.
The only thing that has changed between past usage in cold weather and today is the version of Android I'm using. Unfortunately I'm too lazy to revert to 6.0.1 to see if that solves the issue since I just did a clean install of 7.1.1 about 2 days ago...
What count is the battery temperature not the ambiant one. You can use "cool tool" or wharever app to display that. If you're rooted you can even check the health file I mentionned (to see if it's Cool or even Cold from the model perspective).
The are linked by discharge rate.
The theorical unusable capacity will increase at low and high temperature but also with discharge rate. So if you are at these extreme temperatures, you could try to lower the discharge rate as much as you can by disabling all what you don't need (sync, lte).
Anyway at -23 degres ambiant your battery was maybe at -10 which is outside of its theorical range. We don't know the practical performance at these temps. I'll have to check again to confirm the low temp threshold at which the SOC is not calculated (think 5 degres that is ambiant 0 or -5). Could be that the battery is ok but the software lacks a lookup table at these ranges. There could be a reason. Anyway, I would try to preserve the battery from these temp if you can.
I have the same issue - but in +3 or +4C degrees. The battery went from 60% to zero in 15 min.

Ambiant or battery temperature? If the former, you'll need to know what the battery temperature was. That's the only thing that matters here. I guess you were talking about ambiant so the device once switched on could be at like 8 degrees so I'm surprised about your results.
I use Cool Tool but you can also use any other app like... Battery. What's relevant is battery temp AND battery health (Good, Cool, Cold ).
I've just put my phone in the fridge for some testing. Should be around 4 degrees also
I own a samsung s4 I9505 running lollipop and I think I have temperature issues. I live in Australia with ambient temperatures reaching 30 to 33 degrees on average. My phone can get pretty warm from normal use. The cpu is at 50 to 55 degrees Celsius on normal use and 33 to 40 on idle. The battery can go as low as 28 on idle and 36 on normal use. The phone feels warm to the touch and sometimes uncomfortable. Since getting lollipop it feels cooler for longer but I want to know if this is normal or not considering I'm in Australia. Everything on my device is offical.
Given the ambient temperature, i say it's normal. A protective case should help keep it 2 - 3 degrees cooler as it will stand between your hand and the back of the phone. Hard plastic recommended.
Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the OnePlus 6 stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
Phone has not felt even the slightest bit warm to the touch no matter what I'm doing so far. Like literally stone cold 24/7.
Mine gets hot after playing 3D games. The heat is mostly at the top of the device around the camera area.
Fine in normal use though.
I've played a couple games for a while and it seems to only heat up on graphically intensive, but I mean that's expected. I played the stranger things game for about an hour and it didn't warm up at all. I switched to shadowgun legends, maxed the settings out, and it started getting hot within like 5 minutes. As Joe explained, it gets hot near the camera, but it isn't too bad and it cools down really fast, literally in a minute or so after closing the game.
Yeah, agree with all of the above. I should clarify the game I was playing was Honkai 3rd Impact on max settings which is fairly graphically intensive.
At what temperature does your OP6 hover at.
I don't play games.
As per cpu-z, mine stays between 30.5 to 39 degree Celsius.
(The temp here in Punjab, India reaches 47).
It feels like warmish after I installed Apple music app yesterday.
Before that didn't feel any warmth.
Thanks.

I tested cpu-z for you and got very similar temperatures. I was at around 28°c after turning my phone on. It went to around 31°c when scrolling through twitter and listening to Spotify. And after playing showdowgun legends for a few minutes it got up to 38°c.

Hi..
Could test with the cpu-z app as to what temperature your set reaches when it's the warmest.
Mine has reached almost 39 degrees Celsius when using for everything other than games, for an extended period.
Sometimes though.
Usually it stays around 31 to 35 degrees Celsius on Cpu-z ( its peak summer time here in India, with daytime temperature always above 40).
Above what temperature should one get worried?
Cheers
you "worry" above 80 degrees Celcius, but I dont like it to get much higher than body temp.
I does cool off fast, But it can get really warm sitting in the sun.
I leave mine in a holder on my dash while I drive, playing pandora via bluetooth, and it can get pretty hot.
A few minutes of use, Pandora playing through internal speaker. Heavy JavaScript use on web browser.
It should be noted that my OP6 is Rooted and DeBloated.
Still not clear on one thing.
As to how hot is worrisome?
I spent a full hour browsing Chrome, in a car in a parking lot with no AC on and outside temp hovering at 38-39 degree centigrade,
and my device's battery temp (as on cpu-z app) went to about 41.2 degree centigrade.
I turned the AC on and within no time fell down to 34 centigrade.
Is that normal behaviour?

Of course it's normal behavior if your surrounding temperature is that high
Did you notice, the manual says:
Only operate your phone between 0-35°C temperature and 35-85% humidity

The maximum ambient charging temperature of the equipment declared by manufacturer is 25°C.

Good luck with that in the summer!
I'm finding the screen does get noticeably warm to the touch at the top area near the SoC, just from normal use (such as using Chrome etc). Battery temp rises to about 35 degrees.
A little concerning I'd say.
Another disadvantage of glass back (beside dirt, fingerprints, fragility)
